{"id":"CVE-2026-49495","summary":"Ghidra 10.2 \u003c 12.1 - Denial of Service via Circular Reference in Mach-O Export Trie Parser","details":"Ghidra 10.2 before 12.1 contains an uncontrolled resource consumption vulnerability in ExportTrie.parseTrie() that lacks cycle detection when traversing Mach-O binary export tries. A crafted Mach-O binary with circular references in the export trie causes unbounded queue growth and exponential string concatenation, triggering OutOfMemoryError that crashes the entire JVM and loses all unsaved work.","aliases":["GHSA-wm33-9f68-3vjg"],"modified":"2026-07-08T08:09:42.962744482Z","published":"2026-06-10T12:36:43.369Z","database_specific":{"cna_assigner":"VulnCheck","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49495.json","cwe_ids":["CWE-835"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49495.json"},{"type":"ADVISORY","url":"https://github.com/NationalSecurityAgency/ghidra/security/advisories/GHSA-wm33-9f68-3vjg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49495"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/ghidra-denial-of-service-via-circular-reference-in-mach-o-export-trie-parser"},{"type":"PACKAGE","url":"https://github.com/nationalsecurityagency/ghidra"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nationalsecurityagency/ghidra","events":[{"introduced":"17884b878680e640dd5c30210736a1d062ae5ba2"},{"fixed":"7e89d94e3478f0b1931c34882a0f606fdb06961f"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"extracted_events":[{"introduced":"10.2"},{"fixed":"12.1"}],"cpe":"cpe:2.3:a:nsa:ghidra:*:*:*:*:*:*:*:*"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49495.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
